Has anyone tried out something like this with the Nook Tablet?
From what I've read on Amazon, this thing is sort of lightweight. I was thinking with a slight modification to the bottom of it to add more weight, that it could be a workable docking stand for the Nook.
From what I've read, standard USB cords do charge the Tablet, they just don't charge it as fast as the super nook usb cord...
I have tried half a dozen AC adaptors and cables and the *only* cable I've found that will charge the Tablet is the cable that came with the device.
I'm going off the Settings->Device menu where it tells you if the device is "discharging", "not charging", or "charging".
The Nook Simple Touch AC adaptor will charge the Tablet but *only* when used with the stock Tablet cable.
Plugging the Tablet into the USB port of my iMac using any of my non-stock cables simply changes the status from "discharging" to "not charging", but the charging dialog doesn't come up. It's certainly possible that it's actually charging at this point but at so low of a rate that the device doesn't detect it.
It's also interesting that even though the stock iPad AC adaptor has a higher output than the Nook Simple Touch adaptor (1 amp versus .85 amp), the device will not charge with the iPad adaptor but will charge with the Nook Simple Touch adaptor.
To date I have tried the following adaptors:
Apple iPad - didn't charge
Nook Simple Touch - charged
Nexus One - didn't charge
Stock Nook Tablet - charged
and the following cables:
Nook Simple Touch - didn't charge
Nexus One - didn't charge
generic - didn't charge
Nook Tablet - charged
So to summarize, the Nook Tablet *cable* is the *only* cable I tried that will cause the device to recognize that it is charging. And the Nook Tablet AC adaptor and the Nook Simple Touch AC adaptor are the only two *adaptors* that would cause the device to recognize that it's charging.
As has been noted by many others the extra length of the connector on the stock Tablet cable appears to have something to do with initiating the charge as none of the other cables I've tried even come close to being as long.
Hmm, that's not what I observed. Using a Micro USB cable which came with a Blackberry Curve 8520 works for me. The lock screen on CM7.1 shows charging as soon as I plug it into my PC. I'll check how fast it is charging and report back later.
BTW: The PC has a Gigabyte GA-P67A-UD3-B3 mainboard with Gigabytes special "On/Off Charge Technology" enabled, see http://www.gigabyte.us/products/product-page.aspx?pid=3765#ov
See my post isn the NT 12pin USB Cable post (it is #17 on page 2) for an explanation as to why most cables and some adapters do not work with the Nook Color/Tablet
http://forum.xda-developers.com/showpost.php?p=20842376&postcount=17
Thanks for the hint to your post. I just checked the charging with my Blackberry cable and in 2 hours the charge only increased by 10% (or exactly from 52 to 63% in 125 min). So without the Nook cable you get only trickle charging.
Nook Color charger does it.

I have never used the Nook tablet or cable to charge it. How did I do it...
I have a nook color one, and have used that cable and charger. I was just to lazy to unwrap the new one, just used the old one.

I have noticed the NT only charges when using the AC charger and not when connected to a PC like phones. It even has to use the cable it came with as normal micro usb cables do not work (not for charging anway). Is this right or is this posdibly a hidden setting somewhere I have missed?

The computer does not provide enough amps to charge it. The first day I got mine I plugged the usb into a phone wall charger and it indicated it was charging but didnt seem to be increasing charge. I left it overnight and when I woke up i checked the charge...it didnt budge. I looked at the two wall chargers. The phone charger is a 1 amp charger while the nook charger is 1.9amp. Considering a usb from the computer only provides .5 amps there is no way it will charge.
This is the same as the nookcolor. They use the same charger and have the same limitations.

In addition to the current difference, the cable that comes with the NC or NT has a different MicroUSB end. It is a little longer to reach the higher current pins. There are several discussions in the NC Accessories forum that go into the details.
The NC can charge via pc, as long as the usb hub is powered, or the usb ports are powered, with the provided cable micro usb cable.
Other tablets can charge over .5amp USB so it should work on the NT unless they intentionally designed it to be limited. The Lenovo ThinkPad tablet and iPad both worked via .5amp USB. Just very slowly (had to put iPad in sleep mode).
EDIT: iPad 1 for clarification, never owned the second.

I have a newer motherboard (Gigabyte Z68XP-UD4)
when I plug my Nook Tablet into the front USB, it doesn't charge. But I just plugged it in at about 80% power into the rear USB that was red and labelled "3x USB Power" and it charged WHILE I was transferring files.
I didn't know it was charging until I plugged it into the AC and it showed 100%.
I can confirm it with video evidence if you need it because I'm not one to spread misinformation.
My Giga X58A-UD7 will charge mine too. The option must be enabled in The BIOS in order for the additional Amps to be dispensed. And, it will only work on the onboard (rear) USB ports.
Am I correct in thinking that the USB Standard must include a provision for optional high power pins that may not be present in all USB cables - or chargers?
If I have a standard microUSB cable, can I use my 3x port to charge my NT or do I need to use the special longer connector cable that came with the NT?
Another poster said the Nook USB connector was actually longer, so the high power pins would reach the recessed ones.
Bottom line - don't assume just any cable will work.
Are thenook color and tablet chargers the same? im looking to pick up a spare on ebay,
It's the same thing as the ipad. It will say not charging but it actually does just reaaaaaaaaaaally slow.

They appear to be the same or at least work the same. I have one charger downstairs and one upstairs and the tablet and color charge fine on either one. Just make sure to use the B&N cable, unless you want to wait a while.
So does anybody know where we can pick up chargers cheap? I already have like 5 micro usb chargers and it sucks I cant use them.
AFAIK the NT and NC use the same power supply. My NC with CM 7.1 draws about 600-700 milliamps (according to the Battery Monitor Widget). I have successfully charged it from a PC using a standard micro USB cable. Here's the catch:
- when you connect the tablet to the charger it will turn on. Power down the tablet completely. It will then charge, but takes about 12 hours.
NT uses a 12pin micro USB cable as NC, it seems a special standard, if we use standard 5pin micro USB, only connect to computer is OK, but seems have some trouble to charge, could we find any replacement one?

You'll need to purchase from B&N (unless somebody else can find another source). It is unique. If you look at it, the connector not only has 12 pins, but is longer. The extra length is what initiates contact for charging.
Although its slower to charge attached to the PC (500mA instead of 2A), it does charge. I left mine overnight and it was fully charged using a standard micro-usb cable.
My Samsung Galaxy Tab is like this. There is a software work around that makes it charge faster over USB (see http://forum.xda-developers.com/showthread.php?t=1323957). This gives hope that someday we get similar functionality.

I have heard it will only charge on PC via USB if the screen is off. Otherwise, it uses too much power to really charge it.
What would happen if I put the USB port into a power adapter? I use them to charge my phones when I don't have access to my laptop's USB ports.

I tried using the official Nook cord with an Apple iPad (2 amp) usb charger. The NT never indicated that it was charging.
I tried using a quality micro USB cord with an iPad charger and with the official Nook charger, but it never indicated that it was charging.
I haven't tried a standard micro USB cord to a PC (yet).
So far, only official Nook cord and official Nook charger work for me. Alas.

using the nook cord here with my htc phone charger. all works well
None of my generic USB cords work.
USB Extension cables appear to work with charger
I tried a USB extension cable with the Nook charger and it does work. That means, I think, that the A end of the USB is standard.
I know nobody wants to sacrifice the Nook cable but I'm surprised no one has done this yet. I thought at least the Nook Color cable would be cross-compatible with the NT and someone would have buzzed out the Color cable by now.
There's the bi-color charge LED, but I can't see how they could put a charge chip in there; no room.
This cable is unique....and poorly constructed/misaligned to the 2 prong AC adapter. The USB does not fully insert into the AC Adapter. If not perfectly placed/propped while plugged in to charge, the NT does not charge or charges slowly.
My remedy has been to move the NT closer to the plug so that there is little to no bend in the cable leading to NT.
Will B&N send another if I request online/call? Or, must I unroot and go to a B&N?

Yeah, it's terrible. I don't have any charging issues, but the misalignment causes a ton of electricity to leak, so don't leave it on a couch or a fuzzy blanket unless you want (shockingly) pleasant surprises for hours. I wish they would make an all-in-one-piece as well (do they? would be a good add-on). Sheesh, poor design.
With the billions and billions of 3rd party cords out there, it seems amazing that none exist for the nook tablet. I don't really wanna pay 30 bucks for a backup charger.
2mA too much?
I noticed that the official Nook charger output is rated at 1.9mA - I've just bought a generic 2.0mA USB plug adapter and am hoping that it will work with the existing Nook USB cable. I'm hoping the extra 100mA won't fry the thing...
The extra pins in the Micro end of the Nook USB cable are used to support the higher power draw of the Nook when charging at full rate (2.0A) since the max rated current of a Micro-USB connector is only 1.8A. I am sure they also use the additional pins to make the cable proprietary and possibly also control the bi-color LED. The extra pins are set further into the connector so that they do not cause compatibility problems with standard Micro-USB cables.
In addition to this, the charger brick that comes with the Nook has its Data lines shorted, to each other I believe, to indicate to the Nook that it is plugged into an adapter and not a computer.
The combination of those two things is what is needed for the Nook to charge at its full charge rate. Since the USB A end of the cable is a standard 4-pin design, extension cables that offer all 4 pins/wires will work fine.
The Apple adapter (even the 2.0A version) will not work because it uses a voltage divider (couple of resistors) on the data lines to indicate to the iPod/iPhone what style charger it is (1.0A or 2.0A). One of the data lines is held at 2.1V and the other at 2.7V. Depending on which one (D+ or D-) is at what voltage determines what style charger it is. So the Nook does not recognize the "non-zero" voltage values on the data lines and assumes it is a PC, so it will only charge at 500mA.
Other vendors power bricks use the same "short the data lines" trick as the Nook adapter so several others will work. I believe as mentioned already in this post that HTC uses this same method.
WARNING
Be careful though because if the adapter is rated at less than 2.0A (e.g. 1.0A) you could cause damage or fire. I am not sure if the Nook will slow down charging if it detects the charge voltage dropping if it is trying to pull too much power out of an underrated supply.
If you really want to use your Apple IPad adapter with your Nook Color/Tablet cable you could modify a USB A/A extension cable to disconnect the Data lines and then tie together only the data lines on the side of the cable that will go to the Nook. Again, this can be dangerous, I can not take any responsibility if you attempt to do this.

AdamOutler has confirmed that it will charge on any usb cable, but the tab must be off and it will not show signs of charging. I'm pretty sure that this was charging from the computer.
My device battery is way low.. I'm charging on normal USB so it's trickling up at a rate of about 0x0010 per 2 minutes. At this rate, the device will be ready to use in aproximately 1.5 hours... And until then i'm sure nothing will show on the screen.
This may or may not apply to using the Barnes and Nobel cable. I do not have one available though.
So, if you ever come across a situation where the device won't turn on even after being plugged in, leave it plugged in for a few hours. It could have a case of the "sleeping death".
Also, I'm able to verify that the device... even when totally powered off will charge on a standard USB cable.

Has anyone else had issues with the end that plugs into the nook bending out of place and preventing the cable from working? Since its the cable that is not working and since the tab is still under warranty can I take it back and get the cable replaced for free?

Ahhh... So we can't use a generic power brick or car charger and have the NT charge at full rate (unless we also muck with the USB cable). Thanks for this info!
I'm trying to reduce how many cables and plugs I use. Currently I charge my phone via micro usb, and was wondering if there is an accessory I can buy that will connect from my micro usb cable and into the Prime's proprietary port so I can charge my phone and tablet of a single plug (my phone overnight and then my tablet the next day). I'd much rather have a small adaptor sitting on my bedside table for when I need it than yet another wire trailing across the floor. My plug socket is tucked behind my bed so simply swapping the usb cable each time isn't really do-able.
Many thanks

it is do-able if you used a male to female usb adapter. Then you could just plug in the cable you need to charge with.
I have not seen a micro female usb to full size male? I have seen full size to micro.
You could always get a powered USB hub aswell and have both plugged in. I though I read somewhere that the prime charges best when plugged into the wall though.
I'm going to guess your phone charges at ~5v and the prime will want ~12v (link) ...
There are some reports that 5v will "charge" a transformer, but I'm skeptical ...
More than likely 5v would be more of a trickle charge at a slower rate.
@Tomlilley What did you end up doing?
@copc Interesting idea regarding the powered USB hub. Would the following configuration be possible: TF plugged into a power USB hub and charging, an external HD plugged into the power USB hub with the TF accessing the external HD?
Doesn't USB max out at 5v and Prime is 15v by default (it looks like it charges at 12v as well).
I've got around 4 different micro-USB AC Adapters that I have lying around. One is the OEM Lenovo, One is OEM Samsung (i777 charger + Samsung Micro-USB cable), one is a multi-USB port AC adapter with a micro-usb cable, and the last is an iPad 2 wall charger with a micro-USB cable.
ALL of the chargers except the OEM Lenovo ones don't charge my tablet. When It's plugged in, for a couple of seconds it says Charging (AC), and then it just switches to discharging. I've tried all the aforementioned chargers and cables in different combinations, and the ONLY ones to work correctly is the Lenovo combo.
Is there a specific reason to this? Also tried all 4 cables connected to my PC.. They all don't charge efficiently at all.
look at the Voltage and Amperage of the adapter !
Lenovo use 2A if I remember well, the other use only 1A
quyTam is correct... most USB chargers are between 500mA and 850mA. The dual battery design of the tablets requires a min of 2A to charge correctly. This is why most computer USB ports will not charge the device.
However... the changer isn't the only thing restricting the power. The cable you are using can also effect power. Not all cables are created equal.
I stopped by Staples just after getting my tablet and picked up a 4 port 2.1A USB wall charger. It will charge my phone, Bluetooth, and tablet. There are also really nice 2A "extra battery" devices out there that allow you to a charged battery with you that will power and recharge your device.
I also recommend the dock for the tablet... it has a 65w power supply and charges the tablet in a 1/3 the time then the usb chargers.

i tried 2Amp chargers....didn't help/
my brother says:

as a safety i bought:

just in case...
it costs an arm and a leg for a microUSB charger, but not charging the device for a couple of days would cost me more :S
just another things that makes the TPT slightly less then perfect

Charger
I use a Dell Axim x51 charger and an LG cable from an old phone. Seems to work very well and eBay prices for the charger are less than $4.
http://rootzwiki.com/topic/8523-rev...arger/page__st__40__gopid__448194#entry448194
In my experience a 1A charger will also work. Nothing less than 1A will do anything.
I keep my Lenovo charger in my home office and use a 1A phone charger next to my bed for overnight charging.
I too have a 4 port mains to USB charger: 2A but I thought it was distributed to the 4 ports. If all were being used then each port would only be .5A.
Will have to try it out. If it works it would lighten the travel load of chargers.

The tablet needs to see 5.3 V, when using >500mA.
Already thinner USB-Cables increase the voltage drop
so the thinkpad wont charge, even with the original charger.
It may have less to do with your charger than with the cables. I bought extra long (6 and 10 ft) USB cables for charging phone and my TPT. The 28AWG of any length won't charge the TPT. The 24AWG 6 ft and 10ft cable *will* on a 2A charger. I haven't tried other combinations. I believe it will charge on a 1A charger as well, but would likely require the larger 24AWG cable.

Design Flaw in Thinkpad Tablet prevents Landscape Mode Charging for Developers
I actually sent my 1838-22U in for service, thinking that there was a hardware problem preventing charging while connected via USB. At first I had noticed that while connected directly to a PC via USB for development purposes (no docking station), the unit indicated that it was charging. However, it seemed to be discharging faster than it was charging and slowly worked its way down to unusable. Lenovo Tech Support indicated that they had heard of this happening, and that I should send it in to have its system board replaced. I sent it in only to find that all they had done was replace the battery and reload the firmware. I did notice, however, that when I connected the USB cable, it appeared to go into charging mode for a couple of seconds then switch into discharge mode. I asked Tech Support about this and they said they this was actually the way it should have been behaving all along, and that this was by design.
The User Manual (see attachment) states only that it might not charge, and that it will only discharge if the tablet "exceeds USB 2.0 power limits" (i.e. 500ma).
Well, the Thinkpad Tablet seems to be pretty good at doing that.
Here's where I present to the development community a conundrum. How can one develop in landscape mode while charging (even slowly)? In portrait mode, one can use the accessory docking station, which uses its own charger and charges through the proprietary connector next to the micro USB port, while separately allowing the USB to be used for data. In landscape mode, there is no such option. I will accept that the unit may draw too much current to charge well via a 500ma USB data connection, but then Lenovo should provide a optional charger that connects directly to the same proprietary connector used by the docking station. This is done elsewhere. For instance, Motorola realizes that the Xoom draws too much current to charge via a USB data connection, so they don't even bother with it - they provide a dedicated charger connection and charger.
==UPDATE== 25-May-2012
SOLUTION FOUND
The solution to using a data connection and charging the Thinkpad Tablet at the same time, without relying on the portrait-mode-only Dock Station, is to connect through a powered USB hub which supports the USB Battery Charging Specification (with a Charging Downstream Port). The specification provides at least 1.5A, which quite handily satisfies the Thinkpad. I found such a hub, the GWCTech HU2V40, on Amazon for $15.99.
If you get this model, note that only one of the 4 ports can be used for high-current charging. It includes a tiny "Smart Charger Adapter" but which appears to block the data connection (at least when when used with the Thinkpad). In other words, ignore the little black passthrough adapter included with it, and plug directly in as you normally would. The instructions don't explain the purpose of the passthrough adapter.
Hi everyone!
I just wanted to ask this: I just bought a 90W charger for my laptop. It is a "Targus Compact Charger for laptop and usb tablet"
It charges my laptop and also has that usb port which charges through a cable, compatible devices. Only that on that usb port, it says that it charges 2.1A, which is a lot. My phone charger does only 550mAh.
So the question, shouldn't I charge my phone through the adapter?
Thanks in advance!
I bought this hdmi cable from amazon: http://www.amazon.com/gp/product/B00K61OB6C/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
I hooked up the tab to the tv, cranked up netflix and nothing. I plugged in the power adapter and got a picture. So needs charger to plugged in to work. I wasn't real keen on the output, but was only testing for connectivity. Might come back and edit after I have chance to adjust settings.
Today, I plugged the cable into the second hdmi port on my tv and it does mirror the tab display. Good response time too.
The charger is necessary but it does not charge the Tab. Left it plugged in and battery was down to 38% before i noticed.

Probably not a hardware error. I'm on my 3rd dongle that's supposed to charge your tablet while using connected devices. The latest is this one: http://www.amazon.com/E-More%C2%AE-Multi-functional-Connection-Reader-Samsung/dp/B00K80C9CE/ref=sr_1_8?ie=UTF8&qid=1403104007&sr=8-8&keywords=HDTV+HDMI+Adapter+Cable+USB+OTG+Card+Reader
Everything works except for charging the tablet. Have a red X on the charging symbol while the battery continues to drain. It does charge the tablet while it's off. I have a power hungry Tab Pro 12.2 that has trouble maintaining a charge while playing a couple games with the stock 2 amp charger. I'm beginning to think that none of the HDMI dongles out there are capable of delivering the current necessary to run the larger tablets.
Ah, I see. It's because not enough power through the micro usb. You need 2A but this adapter's only delivering 1A.
It seems, there a no adapters with 2A...
I have a ton of usb chargers gathered over the years. Largest i have is only 5.1 volts. Tab has a large output. Wonder if other devices could be damaged using it or is output regulated by draw of whatever it is attached to? At any rate, i don't think any of the dongles or otg cables have a power source other than what is supplied by the tabs adapter. So are you thinking it is an issue with the pin configuration on the adapter? It is a 11 pin connector. Sure wish there was 1 standard for everyone instead of everyone having their own.

It's not limitated by the pins, there are just for more or less possibilities for an interchange (at least a salesman told me that). It's limited by the inside electronical components. Maybe anybody out there to explain it better or correct my words?
If I remember correctly (it's been a couple years since I tested it), my S3 required the Samsung charger + Samsung wire hooked up to the HDMI (I have the Samsung HDMI adapter) to charge the device while mirroring the screen. I tried it with a more powerful power adapter (2.1 amps vs Samsung 1.x amps) and generic wire but the phone would lose power over time. I could even charge the phone while mirroring if I used a generic Samsung wall charger and Samsung cord that was listed as 0.8 amps.
I bought the official Samsung one a few weeks ago and it is working fine, it also charges the device while using it but you have to connect a charger to the MHL-HDMI adapter.
Sadly I recently flashed CM11 on my TabPRO 10.1 and now the adapter doesn't work anymore. I get picture but no sound Was so happy about getting CM11 official on my device, but this feature is something I can't live without so I'm going to have to hop back to stockbased
HDMI doesn´t work
Hi guys! I´ve bought this one adapter dhgate.com/product/1-1-mhl-11-pin-micro-usb-to-hdmi-cable-hdtv/163941539 I know is not the original one but doesnt work!!!! I did all the steps but nothing. Any idea?? I have installed the original ROM on my galaxy tab t520. I need help!!! Thanks
Hey everyone, so just reading all the comments regarding the HDMI adapter not charging your tab while it is plugged in with the charger, I have also had issues with it and also with my Note2 and the Samsung Smart Dock I use with it. But I did however manage to find the solution to why it would not charge while on the HDMI dock that is connected to my T.V. It seams that if you plug either the Smart Dock or even the HDMI connectors to the HDMI cable first then plug in the charger it will show its charging but will eventually lose charge while outputting an HDMI output, instead, you need to first plug in the charger cable into your HDMI adapter, then plug it into your phone or tablet and finally plug in the HDMI cable into the adapter, I have found this to be the way to keep my phone and tablet charging while also having the HDMI output connected to my T.V..
Hope this helps .
